My invention relates to improvements in transmission gearing for automobiles and particularly to means for lubricating the same.

For the purpose of disclosing my inven-` Fig. 2 is -a plan view of the transmissionYV casing, i

Fig. 3 is a longitudinal sectional view thereof on the line 3-3 of Fig. 2 and Fig. 4 is a transverse sectional view on the line 4 4 of Fig. 3.

In the embodiment illustrated I provide a casing in which the transmission is adapted to be mounted. This casing is provided 20 with a rear end wall 1 having a suitable opening therein through which the power receiving. Shaft 2 is adapted to project and which opening is large enough to accommodatethe bearings 3 for the shaft. The front wall 4 25 of the casing is preferablyremovable and is provided with a bearing 5 and bearing Sleeve 6 through which extends the power delivery shaft 7 of the transmission. Extending transversely between the side walls 8 and 9 of 30 the casing, towards the forward end, are a pair of transversely extending bridges 10 and 11, and an intermediate bridge 12.l These bridges are integrally cast with the Vcasing and the side walls thereof and are connected '35. at their bottoms by a bottom wall 13, thereby forming between the bridges 10 and 11 a pocket the bottom wall of which 1s considL erably higher than the bottom edge of the casing. AThe bridges have Suitable openings w therein to accommodate roller bearings 14, and 16, the purpose of which will appear more fully hereinafter. In the bottom wall 13, on either side of the intermediate bridge 12 I provide openings 17 and 18 the side walls 45 19 of which form the forward edges of wells or pockets and 21 which wells or pockets in effect form scoops for a purpose more fully hereinafter described. The casing has secured to its bottom a suitable oil pan .22

i?? which iS bolted or otherwise secured 'in position and is closed on its-top by a top cover 23 in which is mountedthe. shifter forks, etc., for the transmission. Y

. The power deliveryshaft 7 lprojects into the casing being supported on the bearing 5 545i and'hasat its inner end a'gear 24 which may be integrally formed on the shaft or may be in the form of a gear'secured on the shaft to rotate therewith. The end of the shaft vbeyond this gearis provided with a shoulder 00 25 adapted vto support a gear 26 which is rotatably mounted thereon.V The gear 24 is adapted to drive a counter Shaft in the form Vof a sleeve 27 rotatably mounted on a sta-- tionary shaft 28 on the bottom of'the Acas- '65 ing and extending'through openings in the front and rear walls of the casing. This shaft carries a gear wheel 29 meshlng with the gear 24 and is alsof provided with a pair of gears 30 and `31 adapted to meshrespec- 70 tively with the gears 32 and 33 splined on the.' power receiving shaft 2'. The inner end of. the power receiving 'shaft is'supported in the bearings 16 and is provided-with an internal gear 34. Mounted onthe bearings 14 and 15 75 and eccentrically to the `shafts 2 and 7 is a hollow hub 35 whichcarries at one end any external gear 36 adapted to mesh with the internalgear 34 and at the opposite end an internal gear 37 adapted to mesh with the 80 external gear 26. w Y

Extending through the hub k35 and havv ing its opposite end telescoped'into the-hollowlendslof the shafts 2 and 7 isa supplemental shaft .38 havingat one end external dental clutchteeth 39 adapted when the shaft is longitudinally moved in one direction to engage the internalfdental clutch teethj40. This shaft 38 at its opposite end is provided with an external set ofdental clutch teeth 41 90 constantly in mesh with* an internal set of,y teeth 42 in the hollow end of the shaft 7, and

ywith a second set of teeth 43 adapted, when the` shaft is moved 'longitudinally Vin one' direction to mesh with an internal set of teeth 44 on the gear 26.

In operation by moving the gear 32 into mesh with the gear 30 lthe power receiving shaft will be driven from the power delivery shaft at-'its'lower speed. By Shifting` the gear A10i) `.ceiving'shaft will be driven at its next higher speed. f By shifting the supplemental` shaft- 38 forwardly theteeth 43 will be moved into engagement with the teeth 44 of theV gear 26, theteeth 39 being outof engagement with the teeth 40.` The' gear wheel 26 'wi-llthus 'be locked tothe-:power delivery; shaft l and] f AIn an'automobile transmission the com- .lbination with an enclosing casingylo'f driving "and drivenY zshafts VY:projecting through the power v will be delivered to rthe power receiving shaft 2 from -this gearw26 through the 1n,-

ternalgear 537, thehub 3`r5`,rfth"`e external'gear 36,-the internalgear 34 lto the shaft2.- This will4 drive theshaft 2a`t'its next highe'stH speedor at third speed. yTor-drive the power receiving shaft at'its highest speed the shaft 2 is directly connected tothe shaft 7 by shift` ing ther intermediate shaft l' 3 8 rearwardly' until the teeth i-engage thefteeth 40. yUnder these circumstances.with the teeth 41 and 42 lfin constant mesh. and thef teeth 39 and 40 in mesh, while the'teeth 43 are'out of'mesh with a 5 the teeth` 44 the, power receiving shaftfwill he directlyi driven'pfromfthe power delivery vshown in Fg.'4 are inextremely close prox- V imit'ly tothe shaft 27. .1 v
